- This CEN Technical Report specifies a method for the determination of the mass of water soluble NO3-, SO42-, Cl-, NH4+, Na+, K+, Mg2+, Ca2+ in PM2,5 samples which can be used to comply with Directive 2008/50/EC.This CEN Technical Report describes a measurement method which comprises sampling of anions and cations as part of the PM2,5 particulate phase, sample extraction and analysis of anions and cations by ion chromatography. Alternately, cations, excluding ammonium can be analysed by inductively coupled plasma optical emission spectrometry (ICP-OES).This CEN Technical Report may be used at rural background monitoring sites that are in accordance with the requirements of Directive 2008/50/EC. However, sinceThis CEN Technical Report has not been validated in the field for these, or any other, monitoring site types, it may be considered equally applicable to all site types. NOTE The detection limits described inThis CEN technical report method will be limited by the noise level of the detector and the variability of the mass in laboratory blank filters rather than by the concentrations of anions and cations in ambient air.

URG9000D 高时分辨率的气溶胶水溶性离子在线监测技术
北京市大气环境的持续改善，既有政策的强力推动，又有企业、全民的共同参与。今天飞飞想跟大家聊聊大气颗粒物PM2.5，以及赛默飞在气溶胶水溶性离子在线监测方面的技术。大气颗粒物PM2.5，你知道它都包含哪些成分吗？从化学角度而言，PM2.5组成一般分为水溶性组分、元素组分和碳质组分。水溶性组分中阴离子主要以硫酸盐、硝酸盐和卤素离子存在，阳离子主要是铵根离子、碱金属和碱土金属离子。...
